My object is to render' the operation of moving the seats of such structures as noiseless as possible, and to prevent the binding the seat at its hinged connecsupporting standards in either J vded With position, thereby. prog a onstruction n whichitsseat may eadily moved to swing it towardsor away' from the seat-back with little or no noise.

movement of the and consequently the-head' 31 wih theut 29 in it is spring is centractd suieiently te cause its ehde 27 and28 to strike each other, and thus noise from such cause is avoided. The effect of iorming the spring and disk as described is that oi' preventing any oi the objectionable clicking noise referred to as existing in prior constructions.

' As clearly illustrated in the drawings, the

ree ends of the springs 26 are directed downt wardly, whereby should'a spring break, the i parts thereof will drop, to a position in which i they will not become wedgcd and thereby prevent the, swinging of the seat. The seat may thus. be used even in its impaired coudition.
